We propose to engineer a low-cost computer-controlled optical diagnostic system for measuring sound speed, thermal diffusivity, density, and velocity. This system will use laser-induced thermal accoustics (LITA), a transient-grating technique capable of making accurate single-shot measurements in luminous, multiphase, high-pressure flows. The LITA signal intensity is quadratic in fluid density f ...

THE TREND CONTINUES TOWARDS APPLYING ADVANCED COMPOSITE MATERIALS TO THE HIGH PERFORMANCE STRUCTURES ASSOCIATED WITH AEROSPACE. STRUCTURES FABRICATED FROM CARBON-CARBON AND FILAMENT WOUND COMPOSITES ARE PARTICULAR EXAMPLES. TO FULLY EXPLOIT THE PROMISE OF THESE ADVANCED STRUCTURES, NOVEL NDE TECHNIQUES ARE NEEDED FOR CHARACTERIZATION. DUAL-ENERGY LAMINOGRAPHY SPECIFICALLY ADDRESSES THE CHEMICAL, D ...

The goal of this two-phase program is to develop a prototype system which addresses the problem of nondestructively extracting layout patterns for multilayer printed circuit boards. The system will use x-ray digital tomosynthesis for image acquisition, and advanced image processing, including morphological operators, to extract circuit features from the images. The objectives of Phase I are to 1 ...

Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...

This SBIR Phase I project proposes the development of a real-time IMU simulator which can inject simulated electronic signals into the GPS guidance receiver with least intrusion and is applicable to a wide range of navigation systems. The proposed IMU Simulator consists of a PC compatible microcomputer, a set of plug -in IMU signal generator boards, and a set of general purpose flight simulator i ...

This project will identify and develop new low cost high thermal performance coating systems for composite thermal management materials, particularly high conductivity carbon-carbon. Three materials/processes will be investigated including a new type of chemical vapor deposition called combustion chemical vapor deposition (CCVD), a new proprietary filled polymer having very high thermal conductiv ...

The primary objective of this SBIR effort is to develop and refine UXO detection, location, and discrimination technologies. The development of such technologies are achieved through systematic research, laboratory and bench scale tests, leading to performance validation based on large pilot scale proof-of-principle demonstrations. Results of the feasibility study conducted in Phase I investigat ...

An experimental program to investigate the mechanisms for pulse shortening in high power microwave tubes is proposed. The Phase I effort will develop diagnostic instrumentation and make direct observations of plasma formation and beam phenomena that are probable causes for pulse shortening in the RELTRON (TITAN Corp.). The diagnostics include measurement of gas evolution from the tube components ...

The objective of this proposed Phase I SBIR is to develop the technology that will enable the production of ultra-lightweight, meter class space optics. The research will center on the various destabilizing environments that can affect the long-term stability of precision optics fabricated from polymer matrix composite materials. Several design options will be analytically evaluated for their ca ...

THE RESEARCH ADDRESSED IN THIS PROPOSAL INVOLVES AN INVESTIGATION INTO THE USE OF DIAMOND THIN FILMS AS SOLID STATE OPTICAL SWITCHES WHERE THE FILMS ARE PRODUCED BY AN INHERENTLY LOW-COST TECHNIQUE EMPLOYING PLASMA-ENHANCED CHEMICAL VAPOR DEPOSITION (PE-CVD) OF CARBON-CONTAINING GASES (E.G., METHANE). THE OBJECTIVE OF THIS PROPOSED RESEARCH EFFORT IS TO EVALUATE EXPERIMENTALLY THE OPTOELECTRIC PRO ...
